Local Optical Conductivity of Bilayer Graphene with Kink Potential
Zhen-Bing Dai, Zhiqiang Li, Yan He
We study the optical response of bilayer graphene with a kink potential composed of a domain wall separating two AB regions with opposite interlayer bias. The band structure and th…

Effects of heterostrain and lattice relaxation on optical conductivity of twisted bilayer graphene
Zhen-Bing Dai, Yan He, Zhiqiang Li
We present a theoretical study of the effects of heterostrain and lattice relaxation on the optical conductivity of twisted bilayer graphene near the magic angle, based on the band…

Energy-gap Opening and Quenching in Graphene under Periodic External Potentials
Aihua Zhang, Zhenxiang Dai, Lei Shi +2
In this paper, we investigated the effects of periodic external potentials on properties of charge carriers in graphene using both the first-principles method based on density func…
